We met them two weeks ago when they presented the project in Anderlecht, and we met again at Financité (https://www.financite.be/) today, which coordinates the project. The Zinne is planned to be issued early next year, and will be based on paper notes. They may use a system called Cyclos (https://www.cyclos.org/) for online payment, though this is still in discussion. They were interested in blockchain based technologies, and we will keep interacting with them to see if these technologies could also be of use for the Zinne.
